In a recent study published in Nature, Kehl et al.¹ demonstrate that single neurons in humans specifically respond to the smell of different odours and encode stimulus properties, such as odour identity and valence. Surprisingly, a subpopulation of odour-modulated neurons in the piriform cortex (PC) and amygdala also responds to odour-related images and texts, suggesting cross-modal conceptual representations.

人类嗅觉：单个嗅觉皮层神经元中的气味编码和跨模态概念表示

在最近发表在《自然》杂志上的一项研究中，Kehl 等人¹ 证明，人类的单个神经元对不同气味的气味有特异性反应，并编码刺激特性，例如气味特性和效价。令人惊讶的是，梨状皮层 （PC） 和杏仁核中的气味调节神经元亚群也对与气味相关的图像和文本做出反应，这表明跨模态概念表示。
